75D/72F PLA fiber for underwear

PLA fiber is made from lactic acid derived from starch. It belongs to the type that completes the natural cycle and is a biodegradable fiber. This fiber does not use chemical raw materials such as petroleum at all. Under the action of microorganisms in the soil and seawater, its waste can be decomposed into carbon dioxide and water, without polluting the earth's environment. Since the initial raw material of this fiber is starch, its regeneration cycle is short, approximately one to two years. The carbon dioxide it generates can be reduced in the atmosphere through the photosynthesis of plants. When burning PLA fiber, there is almost no nitrogen monoxide, and its combustion heat is about one-third of that of polyethylene and polypropylene.

Uses of corn fiber:

Polylactic acid fiber is a lactic acid polymer synthesized from lactic acid contained in the human body, and it is safe for the human body. Through testing, circular knitted fabric made of corn fiber does not irritate the skin, is beneficial to human health, and provides a sense of comfort.

Polylactic acid fiber has superior properties, including excellent drapability, smoothness, moisture absorption and breathability, natural antibacterial properties, a weakly acidic property that makes the skin feel at ease, good heat resistance, anti-ultraviolet function, and it is lustrous and elastic. The drapability of PLA fiber fabric, the smooth feeling close to the skin, as well as the softness of the fabric, hydrophilicity, and color luster are all well reflected, giving corn fiber significant development advantages in the fields of close-fitting underwear, sportswear, etc. In 2004, three well-known domestic brands, such as Shanghai Duocai, Qingdao Nuanbeier, and Shanghai Kelefei, had already launched thermal underwear made of corn fiber.

based on the friendly performance of polylactic acid fiber to human skin, as well as the functions of moisture wicking and quick drying, lightweight warmth, and fluffiness and softness brought by special profiled cross-section fibers, it will be widely applied to a series of clothing textiles, including sportswear and leisure wear, school uniforms, underwear, home textiles, baby and children's clothing, gloves and socks, thermal clothing, etc.
